Abstract

The invention relates to a charging and emptying device for a solid rocket motor, which includes a positioning device for ammunition powder columns and a driving device for a water inlet knife rod. The other end of the chuck clamps the grain to be cleaned, and the turntable motor drives the three-jaw chuck to rotate, and then drives the grain to rotate; the linear module is fixed on the mounting seat, and the module slider is used as the output end of the linear module. One end of the rod connecting plate is fixedly connected to the module slider, and the other end is connected to one end of the water inlet knife rod. The other end of the water inlet knife rod is installed with a jet head, and the module motor is installed on the linear module. The slide block drives the knife bar connecting plate to reciprocate, and then drives the water inlet knife bar to clean the inside of the powder column. The invention can quickly clamp and loosen the powder column during the emptying process, and use high-pressure water jet to clean the inside of the powder column, and has the advantages of compact structure, low energy consumption, low noise, high efficiency and safety, good adaptability, simple and convenient manufacture and installation The advantages.

Description

technical field [0001] The invention relates to a high-pressure water jet emptying device, in particular to a solid rocket motor charge emptying device. Background technique [0002] The charge design of a solid rocket motor generally requires it to meet the internal ballistic performance and related constraints of the motor. In the process of rocket engine gunpowder manufacturing and waste gunpowder column emptying and destroying, it is often necessary to empty the ammunition column. At present, domestically, the hot melting method is mainly used for ammunition emptying treatment. Due to the different melting points of various types of mixed gunpowder and the difficulty of melting, the pouring efficiency is low. Secondly, in a high-temperature environment, the chemical properties of ammunition are unstable. Once high-temperature explosion occurs, The consequences will be unimaginable. Contents of the invention [0003] In order to solve the above-mentioned problems exis...
